You know the photo of the all-green R-111 taken from the right front? On the right side it has all the same tools and mods as the camouflaged Ps.231-3 had later. I have no reasons to doubt that the left side should be any different.

So I would say that you can build Ps.231-3 as R-111 with all the mods.
